Miniature rose plant named ‘SAVaboo’

ABSTRACT

‘SAVaboo’ is a new and distinct variety of hardy miniature rose plant, identified by its bi-color blooms of a noticeable bright orange-red offset by the deep yellow at the center and covering the reverse of the petals. The plant is vigorous and a profuse bloomer, making it ideal as a specimen plant, in a border, or in a container.

Genus species: Rosa hybrida.

Varietal denomination: ‘SAVaboo’.

BACKGROUND OF THE INVENTION

This present invention relates to a new and distinct variety of hardy,bush type rose plant of the miniature rose class. This new variety wasdeveloped by me under controlled conditions in a greenhouse in Rowley,Mass., by crossing the following rose plants in the spring of 2000:

The seed parent was a seedling I had developed previously by crossingthe hybrid tea rose ‘TANellis’ (U.S. Pat. No. 2,574) as seed parent withan unnamed, unintroduced miniature seedling from this same hybridizingprogram.

The pollen parent was a miniature rose, ‘Baby Katie’ (U.S. Pat. No.4,471).

The idyllic goal of this breeding program was to produce uniqueabundantly and continuously flowering miniature roses with exhibition,hybrid tea form flowers, and preferably with the qualities of fragrance,disease resistance and hardiness. Both parent roses chosen for thiscross displayed abundant, hybrid tea form bloom production with somedegree of fragrance and above average disease resistance. Additionally,the pollen parent had proven itself quite hardy. (The seed parent wasnot tested for this.)

I harvested and planted 345 seeds from this cross, with 104 seedlingsgerminating. Eight of those seedlings were selected to watch further.The current plant is the only seedling to be tested and introduced; allbut one of the remaining seedlings have been destroyed with that one,along with the current plant, being used in future hybridizing. Thecurrent plant is a miniature rose plant with abundant production ofhybrid tea form, mildly fragrant flowers, good resistance to diseasesand insects, and proven hardiness.

This current plant may be compared with its parents, as shown here inTable 1.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct cultivar of hardy,dwarf, bush type rose plant of the miniature class. The featuresdistinguishing it from its parents and from all other varieties of whichI am aware are its unique combination of the following:

-   -   a bright orange-red flower color set off by the deep yellow        color at the base of and on the reverse of its petals;    -   the length of time these flowers hold their bright coloring;    -   the hybrid tea type form of its flowers;    -   the mild to moderate, sweet fragrance of the flowers;    -   its near continuous flowering habit;    -   its petal count;    -   a plant with uniformly well-branched and slightly spreading        habit;    -   its medium green, semi-glossy foliage;    -   its good resistance to rose diseases;    -   its ability to root easily from cuttings.

The flowers only of the current plant are compared to those of otherbi-colored roses from this same hybridizing program here in Table 2.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations, measurements, values and comparisonsdescribe 1 to 2 year old plants of Rosa hybrida ‘SAVaboo’, of theminiature rose class. These plants began their life in a greenhouse inArroyo Grande, CALIF. At 9 to 12 months of age, they were shipped toIpswich, Mass. where they were grown under lights for 8 months, andfinally moved outside in early June where they were observed for anadditional 12 weeks. Significant differences were noticed between eachlocation showing the phenotypic expression varies with environmental,cultural and climatic conditions. Colors were lighter and less intenseand flower and foliage sizes were larger in locations of lower lightintensity. Descriptions used here are observations of the plants afterthey were outside in Ipswich, Mass., unless otherwise noted. Theinformation is presented here in outline form. Color references are madeusing The Royal Horticultural Society (London, England) Colour Chartexcept where common terms of color are used.

FLOWERS

-   Blooming habit: Fast repeat to near continuous.-   Borne: Mostly singly and occasionally in tight sprays of 2 to 4.-   Bud:    -   -   Size.—About ⅜ inch diameter; about ½ inch long.        -   Form.—Ovate with an acute tip and truncated at the base.-   Color when sepals first divide: A deep Buttercup Yellow, near 15B,    with a Tangerine Orange, near 24C, along the petal edges.-   Bloom:    -   -   Form.—The bloom starts with a flattened upper profile; both            the upper and lower profile became flattened convex, with            the upper profile appearing jagged because of the degree of            quilling of the petals as the flowers matured.        -   Size.—When fully expanded, the diameter is 1 23/32 to 2⅜            inches, with a depth of 20/32 to 1 16/32 inches. Diameter            was directly related to depth.        -   Lasting quality on plant.—In cool temperatures of 60° to 65°            F., petals remained fresh up to 11 days before colors            started to fade, with a total of 16 to 20 days before petals            began to drop.        -   Fragrance.—Mild to moderate, sweet.        -   Petalage.—17 to 27.        -   Petaloids.—None to 8; quantity of petaloids is not relative            to the quantity of the petals.-   Petals:    -   -   Texture.—Adaxial surface was velvety but somewhat rugose;            abaxial surface was more rugose and a bit satiny.        -   Appearance.—The adaxial surface had all veins slightly            recessed, and of a somewhat lighter color than the            surrounding petal surface. The abaxial surface also showed            the veins recessed but with no notable difference in their            color.        -   Form.—Outer petals were broad spatulate with an acute apex            that was minutely notched on either side of the tip.            Intermediate and inner petals were obovate; the apex was            more distinct and the notches on either side were gone or            barely noticeable.        -   Margins.—Of the outermost petals were nearly flat; margins            of the remaining outer petals were obtuse.        -   Size outer petals.—On the full open bloom, widths varied            from 25/32 to 31/32 inch and lengths varied from 28/32 to            29/32 inch.        -   Arrangement.—Imbricated.        -   Persistence.—Remained attached to receptacle until well            after fade, 16 to 20 days.        -   Color.—During the first few days the adaxial surface was a            scarlet red between 46B and 46C. The basal area was a Lemon            Yellow, near 13B. The point of attachment was a deep            Buttercup Yellow, near 15A. The abaxial surface was a            Guardsman Red near 45A along the margins and blended into            the Primrose Yellow, near 4B, from the basal area. It            sometimes appeared near 24B, a Tangerine Orange, in places            where the red from the adaxial surface showed through the            Primrose Yellow. The point of attachment was also near 4B.            The adaxial surface of the inner petals was a bit lighter,            between 46C and 47B. The basal areas and points of            attachment of the intermediate petals were the same as the            outer petals, and of those of the inner petals were near 5B.            The abaxial surface also appeared lighter, near 24C.            Progressing inward toward the center of the flower, the            basal area became more near 5C, a Dresden Yellow, and a bit            darker, near 5B, on the innermost petals. Points of            attachment were near 2B, but near 5B on the innermost            petals. When full open, the adaxial surfaces of all petals            had lightened somewhat to near 43B, a Scarlet Red, with a            few streaks and flecks in the outer petals of a Buttercup            Yellow, between 16C and 16D. Basal areas had become a bright            yellow, between 9A and 12A. The points of attachment were            near 12A. The abaxial surface appeared near 25C, a            Nasturtium Orange. The basal area was near 12A and the point            of attachment was near 14B.        -   Color as the blooms continued to age.—Yellow tones faded            gradually away and adaxial surfaces, most clearly visible,            faded to a Claret Rose near 50B, then to a Neyron Rose near            55B and finally to a Rose Bengal near 57C before the petals            began to drop.-   Petaloids:    -   -   Texture and color.—The same as the inner petals.        -   Size.—Widths varied from 4/32 inch to 23/32 inch; lengths            varied from 7/32 inch to 1 5/32 inches, not relative to            width.        -   Unique characteristics.—The main vein was distinct, always            marked by a yellow streak between 12B and 5C, and was at or            near the center of the petaloid or along one edge. Form was            bifid or cleft at the main vein; distorted, as the lower            portion of a petal with a ragged margin; and/or attached by            a filament. When the main vein was along one edge there            sometimes was an entire or part of a sterile stamen            attached. Any or all of these and other shapes appeared            within each flower at the same time.-   General tonality: Bright orange-red and deep yellow bicolor.-   Sepals: Extended beyond the tip of the bud by 8/32 to 12/32 inch.    They were permanently attached to the receptacle, rolled back just    ahead of the petals, curling back to eventually wrap completely up    around the receptacle, and remained thus as the hip matured.    -   -   Size.—Lengths varied from 17/32 to 21/32 inch on each            flower; widths were most often 7/32 inch varying between            6/32 and 8/32 inch, not relative to length.        -   Color.—Near 144C at the base and center of the outer            surfaces, gradually became darker, between 146B and 147B,            progressing toward the apex. Apices were a very dark            yellow-green, between 146A and 147A. Anthocyanin coloring            was sometimes present, seemingly most often in the cooler            temperatures and absent in warmer temperatures. It may be            strong on the sunward side of the bud near 181A, a medium            color from the Greyed-Red Group, or more often near 176A, a            darker color from the Greyed-Orange Group. Some areas of the            sepal surfaces were flushed heavily, some lightly flushed            and some not at all. Inside surfaces appeared light            grayed-green because of the fine pubescent covering, with            the centers appearing between 194A and 145C, and along the            margins appearing near 191A. Apices were a very dark            yellow-green, near 147A, and without any pubescent covering.        -   Form.—Ovate and truncated at the base. Outermost sepals had            lanceolate apices and inner sepals had attenuate apices.        -   Surface texture and appearance.—Surfaces appear matte. The            surface of the outermost sepals had some randomly located            fine hairs and stipitate glands. As they aged, the stipitate            glands increased in quantity and developed into near evenly            spaced, horizontal, near parallel rows. The innermost sepals            had more hairs covering the surface and a few seemingly,            randomly located stipitate glands that increased in quantity            as they aged, particularly in the basal area.        -   Margins.—Outermost sepals had stipitate glands and hairs            along the margins; the hairs increased in quantity as they            aged. Along each margin were 1 to 3 foliar appendages; most            were broadly serrated with a gland at the tip of each            serrate. Innermost sepals were lined only with hairs and no            foliar appendages.-   Peduncle: Remained firmly attached to the stem until well after it    had dried up.    -   -   Aspect.—Erect, often with a slight curve sunward.        -   Size.—Lengths varied from 23/32 inch to 1 6/32 inches, with            the longest peduncles attached to the longest stems.        -   Color.—A Lettuce Green, near 144A.        -   Texture.—Glossy to semi-glossy.        -   Surface.—Glands and stipitate glands.-   Receptacle: Urceolate.    -   -   Size.—Diameter was uniformly around 7/32 inch; height varied            from 7/32 to 10/32 inch up to and including when the sepals            began to divide.        -   Color.—Noted to be near 144A; or lighter, between 143C and            144B; or even lighter, near 143C, on the same plant on the            same day.        -   Texture/appearance.—Glabrous/semi-glossy.

REPRODUCTIVE ORGANS

-   Stamens, filaments and anthers:    -   -   Arrangement.—Regularly arranged around styles, often in a            double row tightly adjacent to the petaloids.        -   Quantity.—Counted 65 to 93.        -   Filaments.—Length varied from 5/32 to 8/32 inch within each            flower with the longer lengths in the outermost row,            furthest from the pistils.        -   Color.—A Cadmium Orange, near 23B.        -   Anthers.—Color of a Chrome Yellow, near 14D.        -   Pollen sacs.—Color of a Saffron Yellow, near 21A.-   Pistils, styles, and stigmas.—Originated in an alveola in the center    of the top of the receptacle.    -   -   Quantity.—About ⅓ to ½ the number of stamens, counted 24 to            31.        -   Styles.—Thin; the longer ones were sometimes slightly            curled.        -   Length.— 5/32 to 11/32 inch, varied by 3/32 or 4/32 inch in            each flower.        -   Color.—Near 46D, Delft Rose, immediately below the stigma,            and a Naples Yellow, near 11B, as they proceeded into the            alveola.        -   Stigmas.—A dull yellow, between 11C and 162C.-   Hips: Only a relative few were observed to full maturity.    -   -   Shape.—Globoid.        -   Size.—Diameters were measured from 20/32 to 22/32 inch by            23/32 to 25/32 inch; heights were measured from 19/32 to            23/32 inch and also often varied by up to 3/32 inch from one            side of the hip to the other.        -   Surface texture.—Glabrous.        -   Color when mature.—The color when grown under lights varied            from deep orange, between 169B and 169C to a Nasturtium            Orange near 25B on the side with most direct exposure to the            lights. With less exposure the color was less intense and            less orange, near 163C from the Greyed-Yellow Group. The            side away from direct light was a medium green, between 143C            and 144A.-   Seeds: Did not protrude from the top.    -   -   Seed color.—From hips on the plants grown under lights, a            very pale beige, between 159D and 159C, from the            Orange-White Group.        -   Seed shape.—Somewhat oblate, but not smooth or uniform.        -   Seed size.—From these same hips, diameters varied between            5/32 to 6/32 inch by 7/32 to 8/32 inch and lengths of 8/32            to 11/32 inch.

PLANT

-   Habit: Upright, well branched, compact.-   Growth: Very vigorous.    -   -   Size.—10 to 16 inches tall and 10 to 14 inches wide.        -   Root initiation from cuttings.—Under controlled greenhouse            conditions, 3 to 5 days.        -   Length of flowering stems.—Variable, depending on the            distance from the point of origination to the crown of the            plant. Flowering stems originated from other flowering            stems, sometime after the sepals divided, and were usually            one or two inches shorter than the stems from which they            originated. Lengths of flowering stems were measured from 3            24/32 to 4 24/32 inches; flowering stems originating from            those stems were measured 2 24/32 to 3 22/32 inches long;            stems originating from those stems were measured around 1            22/32 inches long.-   Foliage: Pinnately compound, most often with 5 leaflets but also    with 3, 6 or 7. Three-leaflet leaves were usually located as the    last leaf before the connection to the peduncle. Six and    seven-leaflet leaves were usually located at or near the base of the    flowering stems.    -   -   Size of mature leaf.—(Measurements of the foliage are from            the plants when there were growing under lights.) Six- and            seven-leaflet leaves were shorter than other leaves, most            likely because of their location at the base of the            flowering stems. Lengths of five-leaflet leaves varied from            3½ to 4 inches; lengths of 7 leaflet leaves varied from 2½            to 2⅞ inches.        -   Leaflets.—Narrow-ovate, often with a stipel at one or both            sides of the base.        -   Size of terminal leaflet.—On five-leaflet leaves lengths            varied from 1 9/16 to 1 12/16 inches. On seven-leaflet            leaves the lengths were shorter, from 31/32 inch to 1 3/16            inches. Widths on five-leaflets leaves varied from 13/16 to            1 inch; on seven-leaflet leaves they varied from 9/16 to            14/16 inch.        -   Color new foliage.—(Colors of the foliage were very near the            same whether the plants were growing under lights or in            direct sun.) The adaxial surface started a dark green near            139B but, after a day or two, became darker, near 139A; this            was flushed in varying degrees with a dark red, between 185A            and 187A, being most intense on the newly opening foliage.            The abaxial surface was lighter, near 191A, flushed in            varying degrees with Chrysanthemum Crimson, near 185A, on            newly opening leaves, and a darker color, near 187A, as they            expanded.        -   Color older foliage.—Anthocyanin color was absent. The            adaxial surface was still near 139A; the abaxial surface was            darker than on the young foliage, between 191A and 189A.        -   Appearance.—The main vein on the adaxial surface was            completely recessed, with the other veins being somewhat            recessed. All veins protruded on the abaxial surface.        -   Texture.—Adaxial surface was semi-glossy with some long            hairs randomly scattered around the surface. The abaxial            surface was matte and somewhat leathery, with a few long            hairs, sometimes in a cluster, and none to a few stipitate            glands along the main vein.        -   Edge.—Serration was very fine and usually simple, with two            or more serrates sometimes doubled but along only one            margin. Each serrate was tipped with a gland. Randomly, a            stipitate gland appeared between some serrates.        -   Petiole.—Color on the adaxial surface on young foliage was            between 187B and 183A along the ridge and near the same or            somewhat lighter, between 187C and 183D, in the groove. The            abaxial surface was near 187D. On older foliage, the color            on the ridges on the adaxial surface was the same as the            adjacent leaf surface; the color in the groove was lighter,            between 137D and 146C. The abaxial surface was between 138B            and 145B.        -   Size.—On five-leaflet leaves the length varied from 20/32            inch to 1 2/32 inches; on seven-leaflet leaves length varied            from 21/32 to 26/32 inch.        -   Texture/appearance.—Along the ridge of the adaxial surface            were numerous short upright hairs and a few stipitate            glands; the groove had a light covering of these same hairs            with a greater concentration just below the juncture with            the rachis. The abaxial surface had some short hairs and            some stipitate glands, all randomly located.        -   Rachis.—Color of the rachis was the same as that of the            petiole. Size: On five-leaflet leaves lengths varied from            20/32 to 28/32 inch. On seven-leaflet leaves lengths varied            from 14/32 inch to 1 1/32 inches. Texture/Appearance: The            adaxial surface had a few more stipitate glands along the            ridges than were found on the petiole, but the same short,            upright hairs were along the ridges and in the groove. A            larger quantity of these hairs was located just above and            below the junctures of the petiolules. None to two prickles            were found on the abaxial surface, relative to the age and            length of the rachis, but there were several stipitate            glands regardless of age or length.        -   Petiolules.—Color was the same as that of the petiole and            rachis, with the exception that the anthocyanin coloring            took longer to fade. Size: length to terminal leaflets            varied from 16/32 to 19/32 inch on five-leaflet leaves and            from 8/32 to 12/32 inch on seven-leaflet leaves.            Texture/Appearance: Petiolules to the terminal leaflets had            some stipitate glands and a few hairs along the ridges and            only a few hairs in the groove, except for a cluster of            hairs at the base of the juncture with the leaflet. On the            petiolules to the other leaflets, one or two stipitate            glands and a few long hairs were found only along the ridge            closest to the base of the leaf. There were none to a few            long hairs in the groove. On the abaxial surfaces of the            petiolules to the terminal leaflets were a few stipitate            glands and a few hairs, with a cluster of long hairs at the            juncture with the leaflet. Abaxial surfaces of petiolules to            the other leaflets were near glabrous, occasionally having a            few hairs.        -   Stipules.—Paired at the base of each petiole and quite            variable. Size: size was relative to the length of the            petiole to which they were attached. Lengths ranged from            6/32 to 16/32 inch attached and 4/32 to 8/32 inch angled            outward at anywhere from 30° to 90° from the petiole.            Lengths within each pair varied by 1/32 to 3/32 inch.            Lengths angled outward were relative to the length of that            part of the stipule attached to the petiole. Margins:            Sparsely and unevenly serrated, with a gland at the tip of            each serrate, and with glands and stipitate glands randomly            located between serrates. Margins of the tips angled outward            had no hairs and only a few stipitate glands. Edges: curled            back slightly around mid length only.-   Other foliar appendages: At the point where the stem connected with    the peduncle there were one or more simple leaves with stipules    attached the length of the petiole, and/or connate stipulate    appendages.-   Resistance: Above average resistance to blackspot and moderate    resistance to powdery mildew were observed. Downey mildew and rust    were not observed.-   Wood:    -   -   Color new wood.—A Scheele's Green, near 144B.        -   Color old wood.—A darker yellow-green, near 146A.        -   Texture new wood.—Somewhat glabrous; some glands were            present.        -   Texture old wood.—Lenticels formed in the third or fourth            year of growth, starting at the base of the oldest canes, in            parallel, vertical rows. The color of the lenticels was a            medium brown near 165A, from the Greyed-Orange Group.        -   Cane diameters.—About 12/32 inch at the base of the main            canes; 7/32 to 8/32 inch at the base of the primary            laterals; from 3/32 to 5/32 inch, most often 4/32 inch, at            the base of flowering stems, and was not relative to the            length of the stem.-   Prickles:    -   -   Quantity.—1 or 2 between each node. Flowering stems on the            plants growing in MA had no prickles; the accompanying            patent image shows they are present on the plants grown in            the greenhouse in CA.        -   Length.—Between 7/32 and 8/32 inch, most often 7/32 inch.        -   Form.—Angled and gently curved downward, on a near            oblong-shaped base.        -   Color.—When young, the color of the prickles seemed to vary            randomly within the Greyed-Yellow Group: some were between            162D and 160C; some were between 160B and 162B; some were            darker, from the Greyed-Orange Group, near 165B. When old,            the prickles were a dark brown, near 165A.-   Hardiness: This current plant, Rosa hybrida ‘SAVaboo’, has been    tested hardy to Zone 5.
